APPARATUS FOR SPREADING FLY KILLING LIQUIDS ON. A CARRIER Filed Nov, 22, 1927 RSF S'SOVI Patented June 27, 1933 TATES OSKAR .SVENSSON, F DAGLOSEN, SWEDEN APPARATUS FOR SPREADING FLY-KILLING- LIQUIDS ON A CARRIER I Application filed November 22, 1927, Serial No. 235,108, and in Sweden. November 27, 1926.

The usual fly-catching devices for use with a sticky substance or liquid, to which flies adhere, are not suitable in humane and sanitary respects, owing to the fact that the flies, having stuck fast, are tortured during a long period before they die, and after they have collected in" any great number are liable to create a noxious odor. the said drawbacks a killing liquid may be used, to which the flies no not stick but which kills the same in a short time, whereupon they fall down on thefloor, from which they may then be swept away.

The killing liquid must be not too thin and i consists for instance of lubricating oil or generally a distillate from the hydrocarbon group containing a substance noxious to flies and similarinsects dissolved or mixed in the oil or distillate. The active ingredient may consist for instance of ordinary insect powder or an extract of the same, produced for instance by treating the powder with petroleum oil until the oil extracts the poisonous resin or" the'powder the extract being then strained'to remove the inactive constituents.

The said extract kills the flies after they have come into contact with the same.

For spreading the killing liquidon a sur the accompanying drawing may be used.

The said apparatus comprises a receptacle for the liquid and provided in its bottom with a pipe 2 with a. wick 3. In the lower end of with transverse grooves I to give increased surface is fixed by means of a pin 4:. A receptaclefl with cover 7 is suspended in the lower end of the strip. lhe said cover 7 In order to remove.

rend above the surface of the liquid and with face the apparatus shown in a side view in the pipe 2 a strip 5 of veneer and provided 7 trickles continuously downwards on the strip, the latteris always kept Wet and the apparatus is always operative in opposition to the stickyfly-catchers which get dry very soon and become useless. The apparatus may evidently be modified 1n some respects. For instance a valve may be substituted for the wick. The liquid carrier extending downwards from the receptacle 1 may consist of a spiral wire or a plaited wire or of a rod of metal or any other material and wound round with thread or other material.

I claim: An apparatus for spreading fly-killing liquid, comprising a liquid container, a spout 1n the container extending with the upper its nozzle below the bottom of the container, h a wick in the container reaching down through said spout to its nozzle, a band of solid material having one end secured in said nozzle and provided with fine transverse- 1y running corrugations, and a receptacle suspended from the lower end of the band, whereby liquid from said container is drawn from said container by the wick through the nozzle of the spout, spread over the corrugated surface of the band and ultimately collected in said receptacle. I

In testimony whereof I have hereunto afflxed my signature.
